Abstract: 980,652. Valves. WESTINGHOUSE BREMSEN G.m.b.H. Sept. 7, 1962 [Sept. 12, 1961], No. 34300/62. Heading F2V. With a spring-urged piston 2 elevated in its cylinder 1, as shown, a hollow reduced-diameter extension 4 of the hollow piston rod 32 abuts a spring-loaded valve 9 and positions it to place chambers 35 and 36 in communication so that compressed air flows via a valve 14 and chambers 35, 36 to an operating cylinder 18 e.g. of an ironing and pressing machine. Some air flows from chamber 36 through an adjustable needle valve 21 to the cylinder space 20 above the piston 2 until the pressure therein is sufficient to lower the piston 2 in opposition to its spring 5 whereby the valve 9 seats to close off communication between chambers 35, 36 and connect the cylinder 18 to vent via the piston rod 32, piston 2, and ports 29, 30. To reset the apparatus, the valve 14 is operated to vent the space 20 through a check valve 22 whereupon the parts return to the positions shown. The needle valve 21 may be replaced by a slide valve with different sized ports therethrough. The value of the space 20 may be increased by one or more reservoirs 24. The time of the cycle may be varied by adjusting the needle or slide valve, and/or the loading of the pistons spring; the latter is effected by a member 8 screwed on to the cylinder 1, which cylinder is provided with a time scale 31.

Patent GB-448457-A (GB)
Title: Improvements in or relating to the conversion of olefines into sulphuric esters
IPC: C07C303/24
Filed: 1934-12-07
Abstract: The manufacture of sulphuric esters from normally gaseous olefines and sulphuric acid is effected by pumping the liquefied olefine and sulphuric acid through a narrow tubular reaction vessel.  Sulphuric acid of at least 75 per cent strength is preferably used, and the reaction is effected at a temperature between -15 and 40 DEG  C., preferably at about 25 DEG  C.  The reaction vessel may be cooled, either externally or by an inner concentric cooling tube. Overheating may also be counteracted by adding one of the reagents at various points along the tube or by diluting the reaction mixture with a part of the product.  The rate at which the mixture is pumped may be above or below that required to cause turbulent flow. Examples are given in which a liquid hydrocarbon mixture containing 90 or 95 per cent of propylene is pumped with sulphuric acid of 93 per cent strength through a cooled steel coil; the products may be passed directly to a continuous hydrolysis apparatus, and the crude mixture of isopropyl alcohol and water so obtained may be vaporized and passed with air over a hot silver gauze catalyst, whereby acetone is obtained; alternatively, the sulphuric ester may be heated with acetic acid or other organic acid to yield the corresponding ester. The Specification as open to inspection under Sect. 91 states that the reaction may be effected in an autoclave, and includes examples in which such an apparatus is used for the treatment of liquefied propylene with sulphuric acid of 87,5 per cent strength.  This subject-matter does not appear in the Specification as accepted.
Patent GB-959573-A (GB)
Title: Improvements in and relating to methods and apparatus for shaping thermoplastic foils
IPC: B29C51/42
Filed: 1960-10-14
Abstract: 959,573. Shaping thermoplastic sheet material. W. BAHLSEN. Oct. 14, 1960 [Oct. 16, 1959; April 6, 1960], No. 35349/60. Heading B5A. [Also in Division B8] A method for pneumatically shaping thermoplastic foils to close or seal an article or parts thereof, comprises bringing the foil into contact with a heated surface, e.g. a plate 15, Fig. 1, so that it is heated to the required temperature, disengaging the foil from the plate pneumatically and through the agency of a mould which may or may not be cooled, pneumatically shaping the foil into engagement with the article, e.g. a greasing nipple 24, to effect the desired seal, i.e. produce a closure plug 26, and wherein the mould comprises that part of the article which it is desired to close or seal. The plate 15 has heating elements 18, and by means of ducts 19, 20 a vacuum is applied to the foil sucking it on to the heated plate. Subsequently, compressed air is used to form the closure plug 26. It is sometimes necessary to cause the foil to be heated less in some parts than in others, and in Fig. 3 a foil 41 is shown on a plate 40 which has small grooves 42 and larger grooves 43. Above the grooves 43 the foil will only be heated by heat transfer via the narrow webs 44 and will be heated less than that part of the foil above the grooves 42. These grooves can be arranged in a circular fashion or as a raster or network of grooves which are connected to ducts like those shown as 19 in Fig. 3. An alternative method of producing uneven heating of the foil is to either coat the surface of the plate with a poorly conducting lacquer, or to construct the plate of heated and unheated parts. The invention may be applied to closing the ends of containers, as shown in Figs. 10 and 11. Here the end of the container 109<SP>11</SP> is shown fitted with a central pin 116 to form part of the mould. The foil 107 is clamped between the outer peripheral ring of the mould 108<SP>11</SP> and the dome 103. A vacuum pump is connected to the part 106 and the foil is sucked on to the heated plate 101. By now supplying compressed air to the part 106 the foil takes the shape shown in the right-hand half of Fig. 10. For a snap-fitting lid this is sufficient and the moulded lid may be cut from the foil. If complete sealing is required further moulding may be accomplished by movement of the dome 103 downwards against the springs 115 relative to the parts 109<SP>11</SP>, 116 and 101 to mould the foil as shown in Fig. 11. The end of the container 109<SP>11</SP> may be coated with a thermoplastic glue to effect complete sealing on moulding.

[Class 37.] In a thermo-couple temperature-measuring apparatus, errors due to variations in the temperature of the cold junction are compensated for by changing the point of contact on a resistance in a potentiometer circuit or the position of the pen on the recording chart automatically by thermostatic apparatus. The slide-wire circuit of the potentiometer includes the usual slide wire S, Fig. 1, engaged by the slider A and a second slide wire J engaged by a spring contact E carried by a bimetallic strip B, which is mounted at one end on a fixed'abutment F. The thermo-couple T is connected in series with the sliders A, E and galvanometer G. The strip B may be in the form of a spiral or of other shape, or may be replaced by an expanding capsule containing liquid or vapour or by a Bourdon tube &c. Alternatively the contact E may remain stationary and the slide wire J be moved by a bimetallic strip &c. In a modification, Fig. 3, applied to a recording potentiometer the relative positions of the slider A and the pen P are varied in accordance with the cold junction temperature by means of a bimetallic strip M. In another modification, Fig. 4, the slide wire S is carried by two bimetallic strips B, B<1> by which it is moved endwise in accordance with the cold junction temperature.
